One miniature bearing at the center of the top of the central gear of this planet-gear speed reducer by being installed on described planet carrier supports, and support by the bearing that is installed on the described housing middle and lower part of this central gear.
The housing of this planet-gear speed reducer is the bilateral symmetry structure.
Adopted the planet-gear speed reducer of this model utility, owing to adopt the bolt hole of flanged Placement utilization on planet carrier and positioning hole to match with different output shaft, like this behind the output shaft of mixing different-diameter and length, machinery applicable to plurality of specifications uses, can also directly use junction surface and other mechanical connections of speed reducer simultaneously, so not only make the Connecting format variation, and effectively shortened the length of speed reducer; Planet wheel in this speed reducer is installed on the planet carrier, all there is fulcrum at two of planet wheel like this, improved the rigidity of planet wheel, stationarity when the two ends that are installed on planet carrier 4 owing to bearing 7,9 help turning round simultaneously, and the top that miniature bearing is used to support central gear is installed at the center of planet carrier, central gear has the common supporting of top bearing and middle and lower part bearing like this, has changed the cantilever situation of central gear, has improved the rigidity and the transmission stability of central gear; In addition, because all even symmetry of this decelerator body body structure has effectively reduced contingent distortion when making and store later on, thereby has brought great convenience to industrial production.
Description of drawings
Fig. 1 is the internal structure sectional view of planet-gear speed reducer of the present utility model.
Embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also shown in Figure 1, this planet-gear speed reducer, comprise housing 10 and the planet carrier 4, planet wheel 8 and the central gear 13 that are fixedly installed in housing 10 inside, described planet wheel 8 cooperatively interacts with central gear 13 and is connected, wherein, described planet carrier 4 and outside junction surface employing flange-type linkage structure, this structure comprises the positioning hole 2 and the bolt hole on every side 1 at junction surface middle part; This planet wheel 8 is installed on the described planet carrier 4 by a bearing pin 6, and the front end of the mounting hole of the bearing pin 6 on this planet wheel 8 has a small through hole 3 and is connected with the planet carrier 4 junction surface outsides of this speed reducer; The two ends of this planet carrier 4 are fixedly installed on the described reducer shell 10 by bearing 7,9 respectively; One miniature bearing 5 at the center of the top of this central gear 13 by being installed on described planet carrier 4 supports, and support by the bearing 12 that is installed on the described housing 10 middle and lower part of this central gear 13; In addition, the housing 10 of this speed reducer is the bilateral symmetry structure.
In the middle of practical application, for reaching the purpose that makes the multi-form connection of the many specifications of speed reducer, this speed reducer adopts the bolt hole 1 of flanged Placement utilization on planet carrier 4 and positioning hole 2 to match with different output shaft, ought mix the output shaft of different-diameter and length like this, applicable to the machinery use of plurality of specifications.This speed reducer also can not use output shaft and other mechanical connections, and directly uses junction surface and other mechanical connections of speed reducer, so not only makes the Connecting format variation, and has effectively shortened the length of speed reducer, makes it using scope and further improves.
Simultaneously, for a change the cantilever structure of speed reducer strengthens product rigidity, reduces noise and vibration, the stationarity when improving the product running.The planet wheel 8 of this speed reducer is installed on the planet carrier 4, and all there is fulcrum at two of planet wheel like this, has improved the rigidity of planet wheel, and the while is opened the dismounting that aperture 3 is convenient to product like this at the front end of the mounting hole of planet wheel bearing pin 6.Avoided product can only adorn the embarrassment that can not tear open, improving the quality of products for the Installation and Debugging of speed reducer creates conditions.In addition, planet carrier 4 usefulness two bearings 7,9 are installed in the same housing 10, effective like this minimizing because of being installed in the error that different housings causes, simultaneously because the stationarity of the two ends that bearing 7,9 is installed on planet carrier 4 when helping turning round, overcome the defective that in fact same end that traditional speed reducer two bearings is installed on the planet plate has only a bearing to work.The top that miniature bearing 5 is used to support central gear 13 is installed at center at planet carrier 4, and central gear 13 has bearing 5,12 to support jointly like this, has changed the cantilever situation of central gear, has improved the rigidity and the transmission stability of central gear.
In addition, for when processing and storing later on, reducing the distortion of speed reducer itself, this speed reducer adopts succinct all unnecessary external forms of casting out to change, like this because all even symmetry of the structure of housing 10, effectively reduced speed reducer contingent distortion when making and store later on, external form also seems novel, succinct simultaneously.
Adopted above-mentioned planet-gear speed reducer, owing to adopt the bolt hole of flanged Placement utilization on planet carrier and positioning hole to match with different output shaft, like this behind the output shaft of mixing different-diameter and length, machinery applicable to plurality of specifications uses, can also directly use junction surface and other mechanical connections of speed reducer simultaneously, so not only make the Connecting format variation, and effectively shortened the length of speed reducer; Planet wheel in this speed reducer is installed on the planet carrier, all there is fulcrum at two of planet wheel like this, improved the rigidity of planet wheel, stationarity when the two ends that are installed on planet carrier 4 owing to bearing 7,9 help turning round simultaneously, and the top that miniature bearing is used to support central gear is installed at the center of planet carrier, central gear has the common supporting of top bearing and middle and lower part bearing like this, has changed the cantilever situation of central gear, has improved the rigidity and the transmission stability of central gear; In addition, because all even symmetry of this decelerator body body structure has effectively reduced contingent distortion when making and store later on, thereby has brought great convenience to industrial production.
In this specification, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
